It maybe impossible to tell. The same call could be used a signal by
unmated and mated birds. HANZAB doesn't mention anything known about
mate attraction. As cryptic nocturnal birds its a very good bet they do
use calls for mate attraction. The usual "oom" call appears to be used
by both sexes and in multiple contexts. It might well be used for mate
attraction too.
They may have other calls uttered only when there is a nearby
mate/potential mate. I've heard a very different call - probably the
"pulsating call" in HANZAB - from frogmouths sitting side-by-side.
